Random cooling and 3D printing technology
- Product demand for random cooling
The big question is “when do we need to use casual cooling?”In fact, it’s about ROI on the adoption of new technologies, since the costs of new technologies need to be taken into account.In general, there are two products that require the most type-dependent cooling: cup/box products and products with large curvature variations.In addition, for products with uneven distribution of meat thickness, the molding cycle and deformation problems need to be concerned.Nowadays, the quality of products is increasingly demanding, and traditional cooling cannot meet these requirements.Random cooling is the best technique to solve these problems.
- Processing of follow-up cooling water circuit
- Direct metal laser sintering (Direct Metal Laser Sintering) uses laser to sinter metal powder layer by layer to generate core or cavity. This is an ideal method and is commonly used when the core or cavity is small, because metal powders are quite expensive.
- Heat / Pressure technology: Weld two or more metal plates together by heating and pressing in a vacuum furnace.
Relatively speaking, 3D laser printing technology is the best way for processing with cooling water because it can process any shape and has higher design flexibility. But the cost is still high.
- Product demand for follow-on cooling
3D printing technology is based on a computer three-dimensional design model. Through software layered discrete and numerically controlled molding systems, laser powder, hot-melt nozzles and other methods are used to stack and bond metal powder, ceramic powder, plastic, and other special materials layer by layer. Finally, it is superimposed to make a solid product. Unlike traditional manufacturing, which uses molds, turning, milling and other mechanical processing methods to shape and cut raw materials to ultimately produce finished products, 3D printing turns three-dimensional solids into several two-dimensional planes. Reduced manufacturing complexity.
